Our answer
On our planning profile the Anker SOLIX F3000 runs a chest freezer for about 84 hours, or 67 hours if you keep a reserve back.
The checks behind this answer
Stored energy is the final check, not the first. Voltage, continuous output, and startup demand must clear before runtime means anything. Missing published evidence stays marked unverified instead of being treated as a pass.
| Check | Result | Why |
|---|---|---|
| Voltage | Clears | A chest freezer runs on 120V and the Anker SOLIX F3000 supplies 120V AC. |
| Continuous output | Clears | A 110W running load sits inside the 3,600W continuous rating, leaving about 3173% headroom. |
| Startup demand | Clears | The 900W start is covered by continuous output alone, so no surge rating is needed. |
How the number is built
A battery holds back some of its rated capacity, and converting to household AC costs more on top. Of the 3,072Wh rated here, roughly 2,433Wh reaches the outlet under a conservative planning model.
That energy meets an average load of 29W, which applies a 25% duty cycle to a 110W running draw. Holding back a 20% reserve for battery age, cold, and a longer outage leaves 67 hours. These are calculations, not measurements from a test.
Before you rely on this
These limits decide whether this appliance belongs on a portable battery at all.
- A full freezer holds a safe temperature for about 48 hours unopened, and a half-full freezer for about 24 hours. Keep the lid shut and treat backup power as extending that window, not replacing the check.
Replace our assumptions with your own
A full freezer holds temperature far better than a half-empty one, and a freezer in an unheated garage in winter may barely cycle at all. Both change the energy figure substantially.
Read the nameplate or data label for voltage and rated amps or watts, then run the appliance through a normal cycle on a plug-in energy meter for 24 hours. Use the measured watt-hours in the calculator instead of the default on this page.
